Origin & Breeding History: The origin of 'Parella' (experimental designation HZ-97-92) is the result of the cross made in 1996 between RZP 90-2465 and RZ-87-44 at HZPC Research in Metslawier, The Netherlands. The selection criteria included yield, internal and external tuber quality and resistance to diseases and pests.

Tests & Trials: Tests and trials were conducted during the 2011 growing season in Drummond, New Brunswick. Plots consisted of 60 plants grown in a single row with a row length of 18.5 meters and a row spacing of 0.9 meters.
